Title: Amplification suppression for very small signals - uses monitoring device to test all bits and sets only polarity bit to fixed level in PCM system
Inventor: REITZ ERHARD DIPL ING
IPC: H04J3/10
Filed: 1978-09-22
Abstract: The small signals to be suppressed are typically noise and cross-talk signals. The PCM code word consists of a polarity bit and information bits. Bit places in each code word representing the information by the lower voltage level, are set to the lowest level when a monitoring device testing all bits except the polarity bits, detects that these bits represent the lowest voltage level. The monitoring device output signal sets only the polarity bit (b8) to a fixed level, e.g. 1, and prevents it from changing.

Title: Soil improvement implement for growing plants - has double blade to lift and crack soil and break up layer below roots
Inventor: WEICHEL ERNST
IPC: A01B13/14
Filed: 1979-11-20
Abstract: The method of treating the soil in which plants (103) are already growing, so as to improve their growth, uses an implement drawn behind a tractor, with two blades (108,109) one above the other. These are pulled through the earth below the level of the roots, so as to break up a layer (102) below that level (106) into small fragments. At the same time, the blades lift the upper layer so that vertical cracks are formed across. The effect is to aerate and loosen the soil to improve growth. The action can be improved by a blade which precedes the double blade so as to form a starting cut and begin the lifting action. The double blades can be rotated or oscillated by a suitable drive on the framework to which the tools are attached. Auxiliary attachments can be added, including a fertiliser distributor which discharges behind the double blades.
